P0068 2016 Ford F150 Code - Manifold Absolute Pressure/Mass Air Flow Sensor - Throttle Position Correlation

Quick Answer

The P0068 diagnostic trouble code (DTC) indicates a correlation issue between the manifold absolute pressure (MAP) sensor, the mass air flow (MAF) sensor, and the throttle position sensor (TPS). Common causes include Faulty MAP sensor or MAF sensor, Throttle position sensor malfunction, Vacuum leaks in the intake system. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0068 2016 Ford F150 Description

The P0068 diagnostic trouble code (DTC) indicates a correlation issue between the manifold absolute pressure (MAP) sensor, the mass air flow (MAF) sensor, and the throttle position sensor (TPS). In essence, this code suggests that the readings from these sensors do not align as expected, which can lead to improper air-fuel mixture calculations, affecting engine performance. The MAP sensor measures the pressure inside the intake manifold, while the MAF sensor measures the amount of air entering the engine. The TPS monitors the position of the throttle plate, which controls the amount of air entering the engine.

How to Fix P0068 2016 Ford F150

  1. Diagnostic Testing: Start by using an OBD-II scanner to confirm the P0068 code and check for any other related codes.
  2. Visual Inspection: Inspect the MAP, MAF, and TPS sensors for physical damage, loose connections, or corrosion.
  3. Sensor Testing: Test the functionality of the MAP, MAF, and TPS sensors using a multimeter to ensure they are providing accurate readings.
  4. Repair or Replace Components: If any sensors are found to be faulty, replace them. Additionally, repair any vacuum leaks or wiring issues identified during the inspection.
  5. Clear Codes and Test Drive: After repairs, clear the diagnostic codes and take the vehicle for a test drive to ensure the issue has been resolved and that the Check Engine Light does not reappear.

Cost to Fix P0068 2016 Ford F150

The typical repair costs for addressing a P0068 code can vary widely based on the specific issue identified. On average, the cost for parts and labor may range from $150 to $600. For instance, replacing a faulty MAP or MAF sensor can cost between $100 to $300 for parts, with labor costs adding an additional $80 to $150 per hour, depending on the shop's rates. It's important to note that diagnosis time and labor rates can vary based on location, vehicle make and model, and engine type. Most auto repair shops commonly charge between $80 and $150 per hour; however, rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less. It’s advisable to check local rates for a more precise estimate.
